Enhanced Oil Recovery HRSGs

Product Information

NEM can also supply boilers for Enhanced Oil Recovery (EOR) applications with steam injection. EOR is a so-called tertiary oil exploration technique where a medium from outside of the oil reservoir is used to recover crude oil or bitumen which would not have been possible with conventional exploration techniques. Steam injection reduces the viscosity of the oil and increases the reservoir pressure making it easier to recover. Examples of countries with suitable reservoirs for this technique are Canada, Oman, Venezuala, USA and Indonesia.

The most common methods for EOR with steam injection are:

SAGD (steam assisted gravity drainage);

CSS (cyclic steam stimulation);

VSD (vertical steam drive).

NEM can supply steam generators for these processes, both of the once through type and natural circulation type (or drum type). Most common are:

The NEM OT-HRSG is a state of art boiler for co-generation application. It is a very robust design and it is suitable for operation with relatively "dirty" feedwater (e.g. high total dissolved solids (TDS) and hardness). The boiler can be mechanically cleaned if this is required (by the so-called pigging method). The NEM EDL boiler is also suitable for EOR with steam injection if combined with a water treatment plant.
